ELECTRIC LAMP.

Specification of Letters Patent.

Application filed August 19, 1915.

To all whom 'it 'may concern A Be it known that I, ALBERT I-I. SMITH, a citizen of the United States, and a resident of lalaspcth, Queens county, Long Island, State of New York, have invented certain new and useful Improvements in Electric Lamps, of which the following is a specification accompanied by drawings.

This invention relates to electric lamps and particularly to electric lamps adapted for ornamental purposes, such for instance as the illumination of Christmas trees.

The object of my invention is to provide an electric lamp which shall be simple and economical in construction, reliable in operation and attractive in appearance.

In the drawing: Figure 1 is a, front elevation of my improved device; Fig. 2 is a longitudinal sectional view thereof; Fig. 3 is a fragmentary View similar to Fig. 2 on an enlarged scale, and Fig. 4 is a perspective view showing the clamp removed from the socket.

Referring' to the drawing, 10 indicates a hollow cylindrical member preferably of some insulating material, such as cardboarl. rlhis member 10 is adapted toreceive the electrical conductors 1 1 which branch off from the main conductors 12 which are adapted to be connected to some suitable source of current, not shown.

The conductors 11 are connected in any suitable manner to the lamp socket 13 located at the top of the member 10. -This lamp socket, 4best shown in Fig. 4 is provided at the top with a flange adapted to bear against the end of the member 10, as shown in Fig. 3. Cut from the flange 14 are the projections 15.

The clamping member 1G comprises the annular rim 17, and the downwardly projecting prongs 18. In the rim 17 there are formed recesses 19 adapted to receive the projections 15 of the socket 13.

In assembling my device, the clamp 16 is placed over the socket 13, so that the projections 15 coperate With the recesses 19. The projections 15 are then bent over so as to hold the socket and clamp together. These parts are then placed upon themember 10, so that the socket fits into one end thereof, While the prongs 18 extend along Patented. lilla-y 2), serial No. 46,225.

the exterior. Pressure is then applied to these prongs to cause them to penetrate the outer surface and thus positively retain the clamp and socket in position.

The parts having been assembled as above described, they are incloscd and concealed by a sleeve 1Z0 which may be of any desired material. The exterior surface of this sleev(` is preferabliv made to simulate the surface of a candle, so that my device when completed and applied to the object to be illuminated. such as a Christmas tree, is very ornamental as compared with the crude lamp sockets now in general use.

Any suitable lamp 21 may be placed in the socket 13. At the opposite end of the device I provide some suitable means for securing' the device in position, the means here illustrated comprisinga piece of .vire 22, passing;` through holes in the members 10 and F20. I ind that this simple expedient operates 1very satisfactorily for securingl my device to suoli an object as a branch of Christmas tree.

IVhile I have here illustrated but a single one of my improved lamps, it :is to be understood that as many of them as desired may be connected to a corresponding number of branches 11 from conduct-ors 1:2. The several branches may be connected in series or multiple, as desired, depending upon 'the voltage applied to conductors 12, the of the lamps 21, etc. From the above description, it apparent that I have provider an electric lamp wnich is less expensive in construction than the lamps now in common use and is at the same time more attractive in appearance.

I have shown des 'bed a particular embodiment of my improved lamp, but it is obvious that many changes may be made therein by those skilled in the art, "Without departing from the spirit of my invention.

I claim the following:

1. In a device of the character described, a hollow cylindrical member adapts, i to in close electrical conductors, a .lamp socket located at one end of said memlier and connected to said conductors, a clamp overlying the lamp socket and provided with prongs adapted to coperate with said member to retain the socket in position, and a sleeve,

the outer surface of Which simulates a candle adapted 'to surround and conceal .the

member, socket and clamp.

2. In a device of the character described,

a hollow cylindrical member adapted to in-v close electrical conductors, a lamp socket located atone end of said member and connected to said conductors, a clamp overlying the lamp socket and provided with prongs adapted to coperate with said member to retain the socket in position, a sleeve, the outer surface of which simulates a candle adapted to surround and conceal the member, socket and clamp, and means locatedA at the other end of the member and sleeve for retaining the device-in position.

3. In a device of the character described,

a hollow cylindrical member adapted to inclose electrical conductors, a lamp socket located at one end of said member and connected to said conductors, saidsocket being provided at the top with a plurality of pro jections, a clamp for retaining the socket in position, comprising an annular ring provided with recesses for receiving said projections and with prongs adapted to penetrate the surface of said cylindrical member, and a sleeve, the outer surface offtvhich simulates a candle adapted to surround and conceal said member, socket and clamp.

4. .In a device of the character described,

a hollow cylindrical member adapted to inclose electrical conductors, a lamp socket located at one end of said member, and connected to said conductors, said socket being provided at'the top 'with a plurality of projections, a clamp for retaining the socket in position, comprising an annular ring provided with recesses for receiving said pro jections andvwith prongs adapted to-penetrate the surface of'said cylindrical member, a sleeve, the outer surface of which simulates a candle tdapted t surroundand conceal said member, socket and clamp, and
